FIELD OF INVENTIONThe invention relates to a battery swapping station.
PRIOR ARTSAt present, the field of battery swapping of electric vehicles is mainly divided into a chassis battery swapping and a side battery swapping, the side battery swapping is pulling out of the battery pack from the battery swapping vehicle through the battery swapping device, after the plane rotate 180° on the battery swapping device, the electric connection seat turns from facing the vehicle to facing the charging bin, and then insert the battery into the charging bin on the other side of the battery swapping device for charging. Due to the structural constraints of the vehicle itself, the existing method of two-side battery swapping is mostly adopted. To swap the battery on both sides, the battery pack needs to be rotated 180° on the device through the battery swapping device before charging into the charging bin.
However, due to the need to rotate the battery pack in a plane, the elongated battery pack needs a very large space when rotating, which will lead to a complex structure and a large volume of the battery swapping device, which not only directly affects the manufacturing difficulty of the battery swapping device, but also increases the area covered of the battery swapping station, so the electric vehicle can only use the form of multiple small battery packs to swap battery. However, the form of multiple battery packs requires higher cost for the battery packs of the vehicle, and there is a great contradiction in market acceptance, which is not conducive to mass production and promotion.
CONTENT OF THE PRESENT INVENTIONThe technical problem to be solved by the invention is to overcome the defects of the prior arts that the battery swapping station covers a large area, the structure of the battery swapping device is complex, and the cost of the battery is high, hence providing a battery swapping station.

Embodiment 1As shown in
In the embodiment, The battery pack 4 is installed on the electric vehicle 3 to provide power, and the charging bin is arranged in the battery swapping station to provide charging and discharging services for the battery pack, when the battery pack on the vehicle is insufficient to provide power for the electric vehicle to continue driving, it is necessary to replace the battery in the battery swapping station in time, the battery swapping device in this solution is used for the side battery swapping of the electric vehicle, the battery swapping device is located in the battery swapping station, which has both the function of taking and placing the battery and the function of transferring the battery, that is to say, the battery swapping device can take and place the battery from the electric vehicle and the charging bin, and can also transfer the battery between the electric vehicle and charging bin, transfer a discharged battery pack from the electric vehicle to the charging bin, and transfer a fully charged battery from the charging bin to the electric vehicle, in other embodiments, the battery swapping device may only have the function of battery transfer, and the action of picking and placing the battery from the electric vehicle and the charging bin is performed by a separate battery taking-and-placing mechanism.
Using the overturning mechanism 10 in this solution, the battery pack 4 is overturned during the process of transferring the battery pack between the electric vehicle 3 and the charging bin, so as to adapt to the different orientations of the electric connectors in the electric vehicle and the charging bin.
Due to the different positions of the electric connectors in the electric vehicle 3 and the charging bin A, the battery swapping device 1 usually needs to rotate the battery pack 180 degrees to adapt to the position of the electric connector in the electric vehicle 3 or charging bin A, which is applicable to the battery swapping of the electric vehicles which have small size and multi-compartment batteries, resulting in that the battery swapping device needs large space to adapt to the rotation angle of the battery pack, in this solution, the battery pack is overturned vertically by the overturning mechanism of the battery swapping device to adapt to the position of the electric connector in the electric vehicle or the charging bin, which saves the space required for the battery pack to rotate, and at the same time, it can be used for the replacement of large-sized batteries, as well as the battery replacement of electric vehicles with single-compartment batteries, which improves the applicability of the battery swapping device.
The overturning mechanism 10 in the invention rotates the battery pack 4 in the form of overturning. The overturning of the battery pack 4 itself requires less space, and the overturning mechanism 10 can be significantly reduced in structure relative to the battery swapping device 2 that rotates in a plane. Therefore, the battery swapping device 2 of the invention can complete taking and placing of a large battery pack 4 in a charging station within a small space and structure. Therefore, battery swapping for an electric vehicle 3 using a single large battery pack 4 can be realized within a battery swapping station with a small occupied area, such that the cost of the battery pack is reduced, and popularization is facilitated.

The extension direction of the first extension mechanism 111 and the extension direction of the second extension mechanism 121 in the embodiment intersect, so that the battery pack 4 is relayed between the first extension mechanism 111 and the second extension mechanism 121. The battery pack 4 naturally contacts the second extension mechanism 121 after being transported to the end of the first extension mechanism 111. After overturning, the second extension mechanism 121 carries the battery pack 4 for transportation. On the contrary, the battery pack 4 naturally contacts the first extension mechanism 111 after being transported to the end of the second extension mechanism 121.
